I had a really fantastic stay at Koj & Pear's apartment. The apartment is in a new condominium complex with a pool and a small fitness area. The neighborhood is very quiet, set in a residential area with lots of green around. The other residents of the complex were very quiet, and the few that I saw were very nice to me. Koj & Pear were tremendous hosts. The reservation process went smoothly and they responded quickly to my inquiries. At check-in they met me at the entrance to the building and spent 10-15 minutes with me to explain everything. They are a very kind couple and full of information about Bangkok. As for the apartment, it is very modern and clean. The air-conditioners worked well (and quickly!) and the wi-fi was very good. Also in the apartment they prepared a binder with a lot of information about the neighborhood, getting around, restaurants, etc.
It is a slight walk to the nearest sky train station. For me it was around 6-7 minutes, but there was always a little golf cart type shuttle to take guests or pick them up. I actually enjoyed the walk to the sky train through the quiet neighborhood.
Overall, it was a very enjoyable stay and I would stay there again on future trips to Bangkok...
